Tiny Human-Engineered Particles Damages Marine Life

Nanoparticles exist everywhere in our lives – on the fabric of your clothing, the makeup you wear, the display of your TV screen and your car batteries. But when these human-engineered nanoparticles enter the ocean, they can be toxic to ocean life. Jiwoon ParkI am a PhD student in chemical oceanography at University of Washington. […]

Human mercury pollution found at the deepest ocean

For many decades, humans have been putting mercury into the ocean, contaminating big fish like tuna and swordfish. But we haven’t fully realized how deep human-produced mercury could move down the ocean until now – and now scientist have found mercury pollution at the deepest parts of the ocean. Jiwoon ParkI am a PhD student […]

Predicting the future of coral reefs is complicated by human impacts

Coral reefs are often referred to as the “rainforests of the sea” for hosting a great diversity of life, but this incredibly productive ecosystem is seriously threatened by human activities. To better evaluate changes happening in the reef communities and develop strategies to mitigate damages done to coral reefs, understanding how human activities affect our […]

Dust may feed more life in a warmer ocean

Just as our bodies need iron to stay healthy, ocean microbes also need iron to grow. Iron in the ocean largely comes from dust blowing from land, getting sprinkled over the surface ocean and dissolving in seawater. And ocean temperature may be a key factor that controls how much dust gets dissolved into the ocean […]

Ocean plastic pollution damages bacteria that help us breathe

Every minute, we are dumping a garbage truckload of plastic litter into the ocean. Plastic pollution in the ocean are threatening not only millions of marine animals (whales, sharks, turtles and birds), but also marine plants. Toxic materials from plastic are affecting the ability of marine plants to produce oxygen that we breath. Jiwoon ParkI […]

How will climate change affect the Southern Ocean ecosystems?

Changes in the Southern Ocean can affect global climate, and understanding the Southern Ocean’s response to climate change helps us better predict future climate. A team of researchers have looked into this question to predict how human impact on Earth’s climate will affect the Southern Ocean and its ecosystem in the near future. Jiwoon ParkI […]

What your poop says about your diet: Iron in the ocean is controlled by zooplankton diet and poop

Have you ever had weird colored poop? Just like your poop can tell you what you’ve been eating lately, zooplankton poop can tell you what they’ve been feeding on. Iron in zooplankton poop is used as a nutrient by phytoplankton to boost their growth and absorb more carbon dioxide from the atmosphere. Therefore, understanding how […]

Genetically Modified Yeast Can Clean Up Wastewater

Humans have been polluting the ocean with heavy metals by burning fossil fuels, mining metals and discharging wastewater. But we may be able to clean up metals from the ocean in the near future with yeast. Jiwoon ParkI am a PhD student in chemical oceanography at University of Washington. I am studying how different forms […]

    Here at Oceanbites we love long-term datasets. So much happens in the ocean that sometimes it can be hard to tell if a trend is a part of a natural cycle or actually an anomaly, but as we gather more

    Have you ever seen a lobster molt? Because lobsters have exoskeletons, every time they grow they have to climb out of their old shell, leaving them soft and vulnerable for a few days until their new shell hardens. Young, small
